G'day.. i was reading through some forums and i saw this code for a button to move to a different world after it is clicked. However, it says 'cannot find symbol- variable spacelevel1' this is my code:

to change world you should use the code 
World world; 
 world = getWorld();
 Greenfoot.setWorld(new YOURWORLDNAMEHERE());

your code would be
public class Playbutton extends Actor
{
    public void act() 
    {  
        if (Greenfoot.mouseClicked(this)) 
        {
            World world;   
            world = getWorld();  
            Greenfoot.setWorld(new YOURWORLDNAMEHERE()); 
        }  
    }  
}

@trias95, there is no need to get a reference to the world here. You can just use: 
public class Playbutton extends Actor
{
    public void act()
    {
        if (Greenfoot.mouseClicked(this))
        {
            Greenfoot.setWorld(new YOURWORLDNAMEHERE());
        }
    }
}
